It might seem a little odd starting a blog on increasing Invision Community's speed with the word "lazy",  but I'll explain why this is a good word for performance shortly.
Earlier this year, Google announced that page speed is a ranking factor.
Simply put, if your site is slow, it will be ranked lower in Google's search results.
It is always a challenge making a large application like Invision Community as efficient as possible per page load. A single Invision Community page can pull in widgets from multiple applications as well as a lot of user-generated content with attachments, movies and images used heavily. 
This is where being lazy helps.
Lazy loading is a method by which attachments, embeds and images are not loaded by default. They are only loaded when the viewer scrolls down enough to make them visible.
This allows the page to load a good deal faster now it doesn't have to load megabytes of images before the page is shown as completely rendered.
I was going to take a fancy video showing it in action, but it's hard to capture as the system loads the media just before you get to it, so it looks fairly seamless, even with sluggish connections.

Not the most dynamic image, but this shows the placeholder retains the size of the image
In addition to image attachments, we have also added this lazy loading to maps and Twitter emoji images.
Improving non-image attachments
Once we had implemented the lazy loading framework, an area we wanted to improve was non-image attachments.
We have listened to a lot of the feedback we had on this area, and have now made it very clear when you add an attachment into a post. We've even returned the download count now it's being loaded on demand.

Using attachments when posting
All the letters
When we first implemented the letter avatars in 4.3, we discussed whether to use CSS styling or use an image.
We decided to go with an image as it was more stable over lots of different devices, including email.
We've revisited this in 4.4, and switched the letter avatars to SVG, which are much faster to render now that the browser doesn't have to load the image files.
Other performance improvements
We've taken a pass at most areas with an eye for performance, here is a list of the most significant items we've improved.
Several converter background tasks have been improved, so they work on less data Duplicate query for fetching clubs was removed in streams Notifications / follower management has been improved Member searches have been sped up (API, ACP live search, member list in ACP, mentions, etc.). Stream performance has been improved UTF8 conversions have been sped up Elasticsearch has been sped up by using pre-compiled queries and parameterisation, as well as the removal of view filtering (and tracking) HTTP/2 support with prefetch/preload has been added Several PHP-level performance improvements have been made Implemented rel=noopener when links open a new window (which improves browser memory management) Several other performance improvements for conversions were implemented that drastically reduce conversion time IP address lookups now fetch IP address details from us en-masse instead of one request per address Cache/data store management has been streamlined and centralised for efficiency Many background tasks and the profile sync functionality have all been improved for performance Brotli compression is now supported automatically if the server supports it Redis encryption can now be disabled if desired, which improves performance Phew, as you can see, we've spent a while tinkering under the hood too.
We'd love to hear your thoughts. Let us know below!
This blog is part of our series introducing new features for Invision Community 4.4.

We are happy to announce the new Invision Community 4.3 is available!
Some highlights in Invision Community 4.3 include...
Improved Search
We now support Elasticsearch for scalable and accurate searching that MySQL alone cannot provided. There are also enhancements to the overall search interfaces based on your feedback.

 
Emoji
Express yourself with native emoji support in all editors. You can also keep your custom emoticons as you have now.

 
Member Management
The AdminCP interface to manage your members is all new allowing you easier control and management of your membership.

 
Automatic Community Moderation
You as the administrator set up rules to define how many unique member reports a piece of content needs to receive before it's automatically hidden from view and moderators notified.

 
Clubs
The new Clubs feature has been a huge hit with Invision Community users and we are expanding it to include invite-only options, notifications, exposure on the main community pages, paid memberships, and more.
Custom Email Footers
Your community generates a lot of email and you can now include dynamic content in the footer to help drive engagement and content discovery. 
New Gallery Interface
We have reworked our Gallery system with a simplified upload process and more streamlined image viewing.
 
The full list follows. Enjoy!
Content Discovery
We now support Elasticsearch which is a search utility that allows for much faster and more reliable searching. The REST API now supports search functions. Both MySQL and Elasticsearch have new settings for the admin to use to set search-defaults and default content weighting to better customize search logic to your community. Visitors can now search for Content Pages and Commerce Products. When entering a search term, members now see a more clear interface so they know what areas they are searching in and the method of search. Member Engagement
Commerce can now send a customizable account welcome email after checkout. You can whitelist emails in the spam service to stop false-positives. REST API has many enhancements to mange members. Ability to join any OAuth service for login management. Invision Community can now be an OAuth endpoint. Wordpress OAuth login method built in. Support for Google's Invisible ReCaptcha. Groups can be excluded from Leaderboard (such as admins or bot groups). All emails generated by Invision Community can now contain admin-defined extra promotional text in the footer such as Our Picks, and Social Links. Admins can now define the order of Complete Your Profile to better control user experience. Clubs
Option to make a Club visible but invite-only Admins can set an option so any Club a member is part of will also show in the parent application. So if you are in a Club that has a Gallery tab then those image will show both in the Club and in the main Gallery section of the community. Club members can now follow an entire Club rather than just each content section. There is a new option on the Club directory page for a list view which is useful for communities with many Clubs. If you have Commerce you can now enable paid memberships to Clubs. Admins can set limits on number of Clubs per group. If a group has delete permission in their Club, they can now delete empty containers as well. Members can ignore invitations. Moderation and Administration
Unrestricted moderator or administrator permission sets in the AdminCP are visually flagged. This prevents administrator confusion when they cannot do something as they will be able to quickly see if their account has restrictions. You can choose to be notified with a new Club is created. Moderators can now reply to any content item with a hidden reply. Download screenshot/watermarks can now be rebuilt if you change settings. Support for Facebook Pixel to easily track visitors. Moderators can now delete Gallery albums. Automatic moderation tools with rules to define when content should auto-hide based on user reports. Totally new member management view in AdminCP. More areas are mass-selectable like comments and AdminCP functions for easier management. New Features
Commerce now has full Stripe support including fraud tools, Apple Pay, and other Stripe features. Commerce packages can now have various custom email events configured (expiring soon, purchased, expired). Full Emojii support in the editor. Complete overhaul of the Gallery upload and image views. Announcements system overhaul. Now global on all pages (not via widget) and new modes including dismissible announcements and top-header floating bar option. Many new reports on traffic and engagement in the AdminCP. Blog has new view modes to offer options for a traditional site blog or a community multi-member blog platform. The content-starter can now leave one reply to Reviews on their item. Commerce now makes it much easier to do basic account-subscriptions when there is no product attached. Useful Improvements
Forums has a new widget where you can filter by tags. If tags are not required, the tag input box now indicates this so the member knows they do not have to put in tags. Member cover photos can now be clicked to see the full image. Any item with a poll now has a symbol on the list view. Twitch.tv embed support. You can now update/overwrite media in the Pages Media Manager. Mapbox as an additional map provider to Google Maps. Technical Changes
Direct support for Sparkpost has been removed. Anyone currently using Sparkpost will automatically have their settings converted to the Sparkpost SMTP mode so your email will still work. Your cache engines (like Redis) will be checked on upgrade and in the support tool to ensure they are reachable. Third-party applications will now be visually labeled to distinguish them from Invision Community official applications. The queued tasks list in the AdminCP is now collapsed by default as queued tasks are not something people need to pay much attention to during normal operations. When upgrading from version 3 series you must convert your database to UTF8 and the system saves your original data in tables prefixed with orig. The AdminCP now alerts you these are still present and allows you to remove them to reclaim storage space. On new installs there are now reasonable defaults for upload limits to keep people from eating up storage space. Categories in all apps (forums, gallery albums, databases, etc.) no longer allow HTML in their titles. This has been a concern both in terms of security and usability so we were forced to restrict it. Large improvements to the Redis cache engine including use for sessions. The login with HTTPS option has been removed and those who were using it will be given instructions to convert their entire community to HTTPS. Images loaded through the proxy system now honor image limits for normal uploads. We now consider BBCode deprecated. We are not removing support but will not fix any future issues that may come up.
 
There's a lot to talk about here so we are going to lock this entry to comments so things do not get confusing. Feel free to comment on upcoming feature-specific entries or start a topic in our Feedback forum.
 

This entry is about our IPS Community Suite 4.2 release.
We are happy to introduce the next major feature that will be available in IPS Community Suite 4.2 - Clubs.
Clubs are a brand new way of supporting sub-communities within your site. Many people have requested social group functionality in the past and Clubs are our implementation of this concept. Let's take a look at a few screenshots, and then go over what they are capable of doing.

Example of content within a club (topics, in this case)
There's a lot to digest there! Let's go over the basic functionality.
 
Club Types
Four types of club are available:
Public clubs
Clubs that anyone can see and participate in without joining. Open club
Clubs that anyone can see and join. Closed club
Clubs that anyone can see in the directory, but joining must be approved by a Club Leader or Club Moderator. Non-club-members who view the club will only see the member list - not the recent activity or content areas. Private club
Clubs that do not show in public, and users must be invited by a Club Leader or Club Moderator As the site admin, you can of course configure which club types can be created and by whom. You could, for example, allow members to create public and open clubs, but allow a "VIP" group to also create Closed and Private clubs.

Admin configuration option for Club creations
 
Club Users
Each club has three levels of user:
Leader
A leader has all of the permissions of a moderator, and can add other moderators. They can also add content areas (see below). The club owner is automatically a leader. Moderators
Moderators, as the name implies, have the ability to moderate content posted within the club. As the site administrator, you can define which moderator tools can be used. You could, for example, prevent any content being deleted from clubs, but allow it to be hidden. Moderators can also remove members from a club. Users
Anyone else that joins the club.
Defining the moderator permissions available to club moderators
Your site administrator and moderators, with the appropriate permissions, are able to moderator content in any Club regardless of whether they are a member of it. 
Clubs can be created by any user who has permission. As you would expect, this is controlled by our regular permission settings.
For closed clubs, there's an approval process. Users can request to join and the request must be approved by a leader. Leaders get a notification when a user requests to join; the user gets a notification when their request is approved or denied.

Approving and declining join requests
 
Club Content
Club Leaders can add a variety of content areas to their club - forums, calendars, blogs and so on. It's important to note that these content areas are fully functional just as if they existed as a top-level admin created area. They will appear in search results, activity streams, users can follow them, embed links to them, and so on. If a user has permission to see a forum (for example) within a club it will behave exactly like other forums they see - and the same for all other kinds of content.
Each content area a leader adds can have a custom title, and will appear in the club navigation. This means, for example, that you can have multiple forums within a club, and give each a different name.

Adding content areas to a club
 
Club Custom Fields
Clubs also support custom fields. Custom fields are defined by the site administrator and can be filled in by Club Owners. The values they enter are shown (along with the club description) on the club homepage.

Custom fields in a club
On the Club Directory page, users can filter by the custom club fields.

Filtering clubs
 
Club Locations
Clubs have built-in support for Google Maps, allowing users to specify a physical location for their club. Let's say you run a community for car enthusiasts; each club might be tied to a particular region's meetup. The Club Owner specifies the location when setting up the club, and clubs are then shown on map on the directory page:

Club locations
And within a club, the location is shown too:

 
Club Display
We offer two ways to display club headers within the club - the standard way, shown in the screenshots you've seen up to this point, but we also have a sidebar option. This is something the admin sets globally for the site, rather than per-club. This is useful where your site design doesn't facilitate another horizontal banner taking up valuable screen real-estate; moving the club banner to the sidebar alleviates this pressure on vertical space.

Sidebar club style
Using Clubs in Other Ways
There's a lot of scope for using clubs beyond allowing users to create their own groups. You do not even have to call them "clubs" if that does not suit your use case. For example, on a company intranet you could rename Clubs to "Departments", and create a private group for each of your main roles. This would allow each department to have its own community, with its own forums, gallery, file sharing and so on, private and separate from other departments.
Similarly, they'd also work well in situations where you as the site admin want to create entire micro-communities. Take for example a video game publisher. Using Clubs, they could create a micro-community for each of their games, complete with forums, galleries and so forth, and then set the Clubs directory as their overall community homepage. Immediately, they have a setup that hasn't until now been possible out-of-the-box with IPS Community Suite.
 
We expect our clients will come up with some really innovative uses for the new Club functionality, and we can't wait to see what you do. We'd love to hear your feedback - let us know what you think in the comments.
